Based on results of the main test series, the lowest auto-ignition temperature was 419 °C. The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 415 °C.

Conclusions:
The auto-ignition temperature according to Regulation EC No. 440/2008 was determined to be 415 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A.15 and DIN 51794 (2003) to determine the auto-ignition temperature of the test substance. In the preliminary test, an ignition was observed at 435 °C. The temperature determined in the preliminary test was used as starting point for the main test. Three main test series were performed with the semi-automated apparatus ZT3. According to Regulation EC No. 440/2008 method A.15. and DIN 51794 the auto-ignition temperature is regarded as the lowest temperature rounded down to the nearest multiple of 5 °C at which an ignition is observed in any of the main tests. Based on results of the main test series, the lowest auto-ignition temperature was 419 °C. The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 415 °C.

Description of key information

The auto-ignition temperature according to Regulation EC No. 440/2008 was determined to be 415 °C.

Key value for chemical safety assessment
